[RFC] libdispatch (aka Grand Central Dispatch) in base

Hi all,

I'd like to bring up the discussion for topic..

Importing libdispatch (aka Apple's Grand Central Dispatch) into base (contrib?).

Specifically into HEAD then MFC'd only as far back as stable/10.

Here's the reason why:
http://devinteske.com/freebsd-installer-enhancements

Summary:
For the purpose of providing a concurrency model better than pthreads for the
expressed desire to bring about concurrent data processing (applicable directly
to distributions, packages, signing and more).

Multiple people have confirmed with me with respect to the above blog article
that the concurrency model would be most efficient with libdispatch.

Since the tool mentioned in the blog is
a. Compiling with clang
b. Requires newest dialog(3) that is only in stable/10 or higher

I'd say that it looks like a match made in heaven.

But of course, there's that one hang-up... dispatch is not available in base yet.

Is anyone working on getting dispatch into base?
